advice please

got a very small splashback to do at the weekend 2m2 customer has taken old tiles off and the old adh is still on the wall. the new tiles are going a couple of cm higher than the old adh. i have checked the old adh and it is solid to the wall... would i be ok to tile over this????? its only 3 10cm tiles high then up and above the cooker hood. also any advice on how to cut the angled cuts where the cooker hood slopes down... or is it a case of measuring every cut . cheers your help much appreciated ian:stupid:

Get the paint scraper out and remove as much of the old addy as possible. Is it plaster wall? Curved or angled cooker hoods, what a pain, just cut 'em individually. Try and get in there early and whan quoting get the fitter to set the cooker hood off the wall 10-12 mm to allow a tile to slip under/behind it or see if it can be installed after tiling. Gives a better finish.
I tile floors, then kitchen goes in with cooker hood either missing or battoned off the wall. That was after having to cut round a curved glass hood...

Try and scrape off as much old adhesive as possible then tile over, that's what I do.

For tiling upto slopped edges I always use paper templates for the angle, then mark tiles as needed.

so is it defo a no go tiling over the adhesive.... its fairly level. also the cooker hood is just sloped. it is not curved

Theres many who do tile over old adhesive, but some don't like too.

If the adhesive is solid and nearly flat to the wall and no large lumps still stuck out then I'd do a quick sand down, prime, then tile.

those glass hoods are bad news, cut round one looked neat, but now take off

Get a wallpaper stripper(£25)steams the adhesive and ends up like mush,easy to scrape off then.
